We have used web sdk in our web application where both host and participants are forced to use web client to join the meeting. However when we host a session with 400+ participants we ran into an issue where audio and video started to break. This happened for almost all users including host. Later we did the same with 10+ users and experienced the same.  
Majority of the users was using latest chrome on windows and android phones.

Our web app is built using Angular 10

Hey @dryize,

Thank you for reaching out to the Zoom Developer Forum. It sounds like this is related to an ongoing issue with high CPU usage. I was able to find an existing forum post that covers this. As you can see in that post, this is likely related to an existing issue that is slated to be fixed in v1.9.0. Please confirm if you’re seeing high CPU usage when users are encountering audio issues. (ZOOM-179154)

> Hey @anurag, Thank you for reaching out to Zoom Developer Support. I understand that this is a significant pain point when building out an application with the Web Client SDK. As you mentioned, it’s an issue that we have been monitoring and working to resolve for quite some time now. I’m happy to report that version 1.9.0, which will be made Generally Available in early 2021, will bring with it fixes to the CPU usage issues that have been reported. Let me know if you have any questions. Than…

I hope that helps! Let me know if you have any questions.

Thanks,  
Max
